thread blocking hint should be avoided

What steps will reproduce the problem?
if you have an unkown browser like "chromium" installed, the codes of 
BareBonesBrowserLaunch.java cannot recognize it, hence an exception will be 
thrown.

[code]
    public static void openURL(String url) {
        try {
            browse(url);
        } catch (Exception e) {
            JOptionPane.showMessageDialog(null, "Error attempting to launch web browser:\n" + e.getLocalizedMessage());
        }
    }
[/code]

What is the expected output? What do you see instead?
the exception should keep in silent mode, but it launches a heavy 
JOptionPane.showMessageDialog(...) which blocked the main thread.
The user cannot type the pin code if he/she don't close that exception dialog.

[code]              BareBonesBrowserLaunch.openURL(requestToken.getAuthorizationURL());
System.out.print("Hit enter when it's done.[Enter]:");
[/code]

What version of the product are you using? On what operating system?
OS: Ubuntu 10.10
